The battery is connected with a USB interface and a switch. The bottom of battery portion is provided with a solar panel for power generation, and the shell is equipped with a connecting ring and a hook. The invention can solve the problems of abnormal equipment working and current during charging through current display device and the charging failure without direct connection of power supply through solar panel.

TECHNICAL FIELD

The invention relates to the mobile charging field, in particular to a safe multi-directional charger.

BACKGROUND ART

Both charger and charging wire may become faulty or be aging over time which leads to abnormal charging of electronic equipment, the magnitude of output current of charger may become unsafe, and the current output to the electronic equipment to be charged does not meet the current magnitude requirements of electronic equipment. The existing wireless charger includes a charging head directly connected with AC power and a coil for generating induced current. The electronic equipment is provided with an induced coil corresponding to the coil. The charger may become faulty or be aging after it is used, so the electronic equipment cannot be charged normally. Normal charging means that the current of charging head flowing to electronic equipment is within the standard range. However, during use the electronic equipment may show it is being charged but actually it is not normally charged as the current flowing from the charger to the electronic equipment is too weak, but the user cannot judge the safety potential hazard such as charging equipment damage due to abnormal current flowing from the charging head to the electronic equipment. The existing charger cannot be charged when the power is exhausted or the power supply is not directly connected. Single charger can only charge for single equipment but cannot meet the requirement for simultaneous charging of more than one charger.

CONTENTS OF THE INVENTION

The invention can solve the existing technical problems and aims to judge whether the charging current is in safe charging range by checking the magnitude of current of electronic equipment displayed on the current display.

SPECIFIC IMPLEMENTATION METHOD

The attached figures are used below to make a further detailed description that is an explanation rather than a limitation to the invention.

EXAMPLE 1

A safe multi-directional charger includes a shell. A charging portion 1 is arranged on the upper layer of the shell, a battery portion 2 is arranged on the lower layer of the shell, a work coil 11 for wireless charging of magnetic field is arranged in the charging portion 1, and a battery 21 is arranged in the battery portion 2; a current display 12 is arranged on the upper portion of the charging portion 1 and electrically connected with the work coil 11. The shell is provided with an input end 3 directly connected with the electric supply, the input end 3 is electrically connected with the work coil 11 and the battery 21 to supply power to the work coil 11 and the battery 21.

A charging slot 13 is arranged on the upper portion of the charging portion 1 for the placement of wireless charging equipment; clamping units 14 are arranged in the four corners of the upper edge of the charging slot 13.

The electric supply is connected via the input end 3 to supply power to the work coil 11 and to charge the battery 21 that is also electrically connected to the work coil 11 and supplies power. When the input end 3 is not connected to the power supply, the power in the battery 21 is supplied to the work coil 11. When the electronic equipment is wirelessly charged via the work coil 11, the current display 12 shows the current flowing into the electronic equipment.

Clamping units 14 are placed in the electronic equipment in the charging slot 13 for limitation so that it will not fall along the vertical direction of the charger plane but will slide into and out of the electronic equipment along the horizontal direction of the charger plane.

At least one USB interface 22 is arranged outside the battery portion 2 as the output end and outputs power from the battery 21, a switch 23 is arranged on the same side of the USB interface 22, electrically connected with USB interface 22 and outputs power of the battery 21 to the USB interface 22; the output end of the battery 21 to the USB interface 22 is electrically connected with the current display 12.

The connection and disconnection of the battery 21 and the USB interface 22 are controlled by the switch 23, and the USB interface 22 can directly charge the electronic equipment via the USB connection line. An indicator lamp is furnished on the circuit controlled by the switch 23 to observe whether the USB interface can be charged. When several USB interfaces 22 are used, more than one piece of equipment can be powered simultaneously by battery 21.

The solar panel 4 is arranged at the bottom of the battery portion 2, electrically connected with the battery 21, and charges the battery 21.

A cooling fin is also connected to the battery 21, which generates heat when the battery 21 works, and the cooling fin plays a major role of heat dissipation to protect the equipment safety, especially when more than one piece of equipment is simultaneously charged on the charger using the battery 21. The more heat it generates, the more significant heat dissipation effects it produces.

Four connecting rings 5 are arranged in the four corners at the lower portion of the shell, and the four lower planes of the connecting rings 5 protrude downward compared with the solar panel 4; hook 6 is arranged outside the shell.

When the battery 21 is out of power or has no power input, the solar panel 4 can generate power and supply it to the charger, and a rope or a belt on the connecting ring 5 can be used to fix the charger or connect it to a place where it is needed to enable the function of facilitating placement of the charger, and the hanger 6 can be hooked on the item at will, and can also enable the function of facilitating placement of the charger.

The lower plane of the connecting ring 5 protrudes downward compared to the bottom surface of the solar panel 4, and when the charger is placed, there should be a gap between the solar panel 4 and the place where it is placed, to prevent wear and tear caused by movement or collision from occurring on the solar panel 4.

Setting the input end 3 as a USB port makes it easy to charge the charger in various ways under different circumstances.

The current display 12 can be a digital display ammeter or a pointer type ammeter, to personalize the charger and meet different people's preferences.

A method that monitors whether charging is normal with the above charger. The steps are as follows:

1): arranged a current display 12 at the output end of the charger;

2): use the current from the charger when charging on the current display 12;
